Way better for camper shells than track s.



by:

It’s the bomb. Great design. Well made.



by:

Nice and sturdy but was a PIA to install… prepare to give yourself a few hours to button this up securely on your roof.



by:

Best price on the part. Fast shipping. The install video made it a breeze. Rhino rack was a little lazy with the written directions and stamping all the parts. The etrailer video for 2015 JKU was needed.



by:

Quick, A+ thanks



by:

Best backbone I could find for a custom build. Flat lower profile more practical for my needs. Thanks guys!



by:

Just as I had expected. Top quality and no rust. A bit scary drilling the holes in your top but all went well. Their anti theft allen screws could use an upgrade.



by:

Great quality and was easy to install as the directions were simple to follow.



by:

The backbone rails look great! However, the instructions need to be revised to include information that is Armada specific. Instructions for removal of factory rack is not included and not available anywhere I could find on the internet. It’s almost impossible to remove the end caps on the factory rack without destroying the tabs that hold them in place. Also, the middle connection point of the backbone has 2 bolts, the factory rack only has one. However, the second hole is there but you must remove the trim piece that sits below the factory rack. It’s simple to remove and reinstall without damaging the clips. In order to make the backbone rails fit, you have to cut an additional couple of inches from the existing window in the trim piece in order to expose the second hole underneath. This is pretty simple with the right saw but some additional instructions on this would be helpful. Overall, this is a great product, just need to make customers aware of the extra steps needed on the Armada vs the installation on the Nissan Patrol.



by:

This system is great. Have a 6’ rack mounted to it and it easily supports 200-300lbs of dynamic load a d 700+ static load without issue.



by:

I love how this rack system uses the existing holes in the roof for mounting. Exactly what I was looking for. It makes for a very clean look.



by:

Always great products by RhinoRack and excellent service from eTrailer….!



by:

The product I ordered from etrailer arrived in tact and and in good timing.



by:

Product was exactly what was expected with no damage or defects. E-trailer staff were very helpful and informative in regards to the status of the order.



by:

This is a pretty great platform. It has held up fine, doesn't leak, and wasn't too bad to install myself. It looks nice, and is there when I need it.



by:

Perfect fit and finish for 2016 Chevrolet Suburban.



by:

Great product! I have had no issues



by:

This product is excellent but the instruction have a lot to be desired

  • What Roof-Mounted Platform do You Recommend for My 2022 Toyota 4Runner?
    I have a great platform solution for you. Unfortunately, I confirmed with Yakima that they have not confirmed a fit of the LockNLoad Platform # Y05045 on your factory crossbars on your 2022 Toyota 4Runner. With that being said, Yakima also has not tested the fitment of the LockNLoad to your rails if you remove the crossbars from the setup. This is because manufacturers often do not test these applications because their reasoning is you will always use your factory crossbars with any application....

  • Low Profile Roof Platform Recommendation for 2020 Toyota 4Runner with Factory Side Rails
    For your 2020 Toyota 4Runner with the factory side rails, I recommend the Yakima LockNLoad Platform Roof Tray 60" Long x 54" Wide, part # Y05045. It's pretty low profile at only 4 inches tall, and it will not interfere with your sunroof, since it will sit right behind it. I've attached a couple of photos so you can see for yourself. To attach the platform, you'll need the LockNLoad SL Adapters # Y05042-2 (qty 4), and TimberLine Towers # Y33TR (qty 4). This will add approximately another...

    The correct part number for the Rhino-Rack Backbone Mounting System RT4B1 is # RRRT4B1. As for the 52107F, I can confirm for you this part is the 84" Long x 49" Wide Rhino-Rack Pioneer Platform Roof Tray # RR25TB.

  • Rhino-Rack Pioneer Platform Roof Rack Mounting To a 2021 Ford Explorer
    Currently the only mounts for your 2021 Ford Explorer to add a Rhino-Rack Pioneer Platform Roof Tray # RR95TB are the Rhino-Rack SX Series Legs # RRSX100. These legs will attach to the factory raised rails that are on your Explorer and hold the Platform in place. There are no Rhino-Rack Backbone Mounting Systems for your Explorer.

  • How to Mount 60 Inch x 49 Inch Rhino-Rack Pioneer Platform Rack to 2018 Toyota 4Runner
    I spoke with my contact at Rhino-Rack regarding the Rhino-Rack 60 Inch x 49 Inch Pioneer Platform Rack # RR35TB and your 2018 Toyota 4Runner. She stated that in order to use this size Pioneer Platform Rack on the roof of your 4Runner, you will need to actually keep the factory side rails and use the Rhino-Rack SX Series Legs # RRSX100 to mount the Platform. The Rhino-Rack Backbone Mounting System # RRRT4B1 that is designed for your 4Runner is only compatible with the larger size Pioneer...

  • Recommended Rhino Rack Pioneer Platform for my Toyota Sequoia 2016
    I have a great solution but there is no available backbone system for your 2016 Toyota Sequoia from Rhino Rack. Instead the Rhino-Rack Pioneer SX Platform Rack part # JA8011 is a confirmed fit for your 2016 Toyota Sequoia this is designed to clamp on to your already existing raised factory side rails.

  • Can I Mount the RR45TB on a Customized Backbone Installation on a 2007 Nissan Pathfinder?
    I have a platform answer for you. I went ahead and confirmed with Rhino-Rack that they unfortunately do not make an engineered fitment of a Backbone Mounting System or a Pioneer Platform with a 2007 Nissan Pathfinder. Everything you decide to do with the backbone is considered a non-approved fitment. With that being said, it depends on the length and model of Backbone you want to have installed on your roof. This is important because each size platform is designed to go with a specific...

  • Correct Rhino-Rack Pioneer Platform Roof Tray and Backbone Mounting System for a 2022 Toyota 4Runner
    I went ahead and checked with Rhino-Rack, and the good news is both the Rhino-Rack Backbone Mounting System for Pioneer Platform # RRRT4B1 and the Rhino-Rack Pioneer Platform Roof Tray # RR25TB are compatible with each other as well as your 4Runner. This Pioneer tray measures 84" long and 49" wide, however if you want a smaller platform you could use the Rhino-Rack Pioneer Platform Roof Tray # RR45TB which is 76" long and 49" wide. This platform is also compatible with the backbone #...

  • What Roof Trays Does Rhino Rack Backbone System Fit on 2016 Toyota 4Runner
    The Rhino Rack Backbone system # RRRT4B1 that you referenced can only be used with Pioneer Platform roof trays like with the part # JA9328 for a tray that measures 76 by 49 inch or the # JA9133 which measures 60 by 49 inch.
